Kemi Badenoch inheritance tax plan: Could the Conservatives really scrap the 40% levy?

Inheritance Tax is back at the centre of Britain’s political debate after Conservative leader Kemi Badenoch signalled that abolishing the levy could become a major Tory policy if the party can make the finances work.

The proposal would mark one of the biggest potential changes to the UK’s tax system, particularly for families with valuable homes, businesses, farms and other assets. But despite growing political pressure to scrap the tax, abolition is not currently government policy and would require a future Conservative administration to find billions of pounds to replace the lost revenue.

Reports suggest Badenoch is considering announcing an abolition plan at the Conservative Party conference in Birmingham next month. The Conservative leadership has stressed that no final conference policy has been decided and that any tax cut would have to be fully costed.

The debate is gaining attention because Inheritance Tax has remained politically unpopular while the value of estates affected by the frozen thresholds has increased.

What Is Inheritance Tax?

Inheritance Tax, commonly known as IHT, is a tax on the estate of someone who dies. An estate can include property, savings, investments, valuables and other assets.

The standard rate is currently 40%, but it does not apply to the entire estate automatically.

For the 2026-27 tax year, the standard tax-free threshold, known as the nil-rate band, is £325,000. The government has also kept the residence nil-rate band at £175,000 for qualifying estates.

This means some people can potentially pass on significantly more than £325,000 without paying Inheritance Tax, particularly when a qualifying home is passed to direct descendants.

How Much Can You Pass on Without Inheritance Tax?

The rules are more complicated than the headline £325,000 figure suggests.

A qualifying estate may receive an additional £175,000 residence nil-rate band when a home is passed to children, grandchildren or other direct descendants.

Unused allowances can also be transferred between spouses or civil partners.

That means a qualifying married couple or civil partners could potentially pass on up to £1 million without an Inheritance Tax charge, subject to the relevant conditions.

The residence allowance is subject to a taper for estates worth more than £2 million, reducing the additional allowance as the value of the estate increases.

Why Is Kemi Badenoch Considering Scrapping Inheritance Tax?

Badenoch has previously described abolishing what she calls the “death tax” as a high priority.

The latest proposal reflects a wider Conservative argument that families who have already paid taxes during their lifetime should not face another substantial charge when wealth is passed to the next generation.

Supporters also argue that the tax can affect family businesses, farms and homeowners whose assets have increased substantially in value over several decades.

The political appeal is clear: abolishing IHT would give the Conservatives a major tax-cutting policy and create a sharp dividing line with Labour.

But the financial question is harder.

How Much Would Abolishing Inheritance Tax Cost?

The cost of scrapping Inheritance Tax has been put at around £9 billion a year in the political debate surrounding the proposal.

That money would have to be replaced through spending cuts, higher receipts elsewhere, stronger economic growth or some combination of the three.

Badenoch’s team has indicated that abolition would only happen if the numbers add up.

That qualification is significant. A Conservative government could announce an intention to abolish IHT, but turning that promise into policy would require a detailed fiscal plan showing how the Treasury would absorb the lost revenue.

The Conservatives have also faced criticism from opponents who argue that the biggest beneficiaries would be households with substantial estates.

Why Has Inheritance Tax Become So Controversial?

One reason is the long freeze on the main tax thresholds.

The £325,000 nil-rate band has remained unchanged for years, while the value of homes and other assets has risen substantially in many parts of Britain.

The residence nil-rate band is also fixed at £175,000. Current legislation keeps the main thresholds at these levels through 2030-31.

That creates what critics describe as a form of fiscal drag: estates can become liable for IHT without the family necessarily becoming wealthier in real terms.

A home that was once comfortably below the tax threshold can become part of a taxable estate after years of house-price growth.

Who Would Benefit Most If Inheritance Tax Were Abolished?

The biggest direct beneficiaries would generally be estates currently facing an IHT liability.

That could include families with expensive properties, investment portfolios, large savings balances, businesses and agricultural assets.

Families with estates below the relevant allowances would see little immediate difference because they already pay no IHT.

This is one reason the policy is politically divisive.

Supporters see abolition as removing a tax on wealth that has already been taxed during a person’s lifetime. Critics argue that removing the levy would disproportionately benefit wealthier households because lower-value estates already fall outside the tax.

What Would Happen to Family Homes?

Abolition would remove the IHT liability that can arise when a taxable estate passes a family home to beneficiaries.

Under the current system, however, a qualifying family home can already benefit from the residence nil-rate band.

The additional allowance is generally available when the property is passed to direct descendants, subject to eligibility requirements and the £2 million taper threshold.

For a qualifying couple, unused allowances can also be transferred, potentially allowing a larger amount of wealth to pass without IHT.

That means any Conservative plan to abolish the tax would need to address how existing exemptions and allowances would be replaced or simplified.

Could Kemi Badenoch Actually Abolish Inheritance Tax?

It is possible, but it is far from guaranteed.

The Conservatives would need to win a general election and then introduce legislation. They would also need to demonstrate how the lost revenue would be covered.

The party has made clear that it does not want to announce unfunded tax cuts.

That leaves several possible outcomes: complete abolition, a substantially higher threshold, changes to reliefs, or a phased reduction in the tax rate.

A future Conservative government could also decide that raising the threshold delivers much of the political benefit without the full £9 billion cost of abolition.

What Could Happen Before the Next Budget?

For now, the current Inheritance Tax system remains in place.

The standard rate is 40%, the main nil-rate band is £325,000 and the residence nil-rate band is £175,000 for qualifying estates.

The Conservatives have not formally confirmed that abolition will be included in their final conference platform.

That makes the coming months important for anyone watching the policy debate.

If Badenoch does unveil a fully costed abolition plan, Inheritance Tax could become one of the clearest dividing lines between the Conservatives and their political rivals.

For families planning estates, however, the immediate rules have not changed.

Any decision to abolish the tax would depend on the outcome of future political and parliamentary processes.
